The light absorption abilities of fluorescent brighteners were characterized by UV-visible spectrometer, the photochemical properties of them were analyzed by fluorescence spectrometer and electron spin resonance , the photoinitiation efficiencies of the photoinitiating systems were monitored by real-time Fourier transfrifm infrared spectroscopy , meanwhile , the fracture surface morphology and surface morphology of the products obtained from the concomitant cationic/radical photopolymerization of epoxides/acrylates blends were observed and analyzed by scanning electron microscope and atomic force microscope, respectively.

New discoveries in chemical research and development in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.6825-20-3, Name is 3,6-Dibromo-9H-carbazole, molecular formula is C12H7Br2N.

Cancer is a major health problem and the most upsetting disease in humans, leading to death in both developed and developing countries. Proper treatment of the disease is still a challenge. Chemotherapy is considered one of the regimens to cure this disease. In this study, a series of 1,2,3-triazole and isoxazole-linked benzothiazole/benzoxazole derivatives were synthesized and evaluated for their anticancer activity against human cancer cell lines, such as HeLa (cervical), and A549 (lung) cell lines, with HEK-293 cell line used as a control. Among them, conjugates 8a, 8f, 13g, 13h and 13j displayed significant cytotoxic activity against human cancer cell lines. Furthermore, these active conjugates induced an increase in the expression of key apoptotic genes that are involved in the intrinsic pathway of apoptosis such as caspase-9, caspase-3, BAX and cytochrome-c. This study may provide possible anti-cancer therapeutics against HeLa and lung cancer cells.

Benzothiadiazole (BTD) dyes are an important class of N,S-containing heterocycles that have remarkable optical properties. In this work, two new 2,1,3-benzothiadiazole dyes conjugated with benzothiazole and benzoxazole moieties were synthesized and the optical properties in solutions and in the solid state were investigated. The BTD dyes were synthesized in a single step from cydization of ortho-diamino benzothiazole and ortho-diamino benzoxazole dyes. The photophysical behavior of BTD precursor’s benzoxazole and benzothiazole dyes were also investigated. The dyes present absorption in the UVB (280-315 nm) and UVA (315-400 nm) wavelength and fluorescence in the blue-green visible region. The solvatochromic properties of the dyes were investigated indifferent solvents taking into account the solvent orientation polarizability (Delta f) and E-T (30) polarity solvent parameter. The ground and excited state dipole moments were determined by applying Bakshiev’s and Kawaski-Charnma-Viallet’s formulations. Furthermore, the spectroscopic properties of thin films and powders of BTD dyes were explored. (C) 2020 Elsevier B.V. All rights reserved.

A novel series of 1,3-benzoxazole and 1,3-dioxolane substituted benzimidazole-based N-heterocyclic carbene (NHC) precursors (6a-b and 11a-b) and their corresponding NHC-silver(I) acetate (12a-b and 14a-b) and bis-NHC-silver(I) hexafluorophosphate complexes (13a-b and 15a-b) were synthesized and characterized by H-1 NMR, C-13 NMR, ATR-IR spectroscopic methods and elemental analysis techniques. Also, the molecular structure of benzimidazolium salt (6a) and bis-NHC-silver(I) hexafluorophosphate complex (13b) were unambiguously established by single crystal X-ray diffraction analysis. Fascinatingly, bis-NHC-silver(I) hexafluorophosphate complex (13b) was revealed to be dinuclear in nature. All the azolium salts (6a-b and 11a-b) as well as the corresponding silver(I) complexes (12a-b, 13a-b, 14a-b and 15a-b) were evaluated for their antimicrobial potential against Gram positive (Staphylococcus aureus), and a set of Gram negative (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) bacterial strains and two fungi, Candida albicans and Cryptococcus neoformans. Antimicrobial studies revealed the comparable activities of benzimidazolium salts (6a-b and 11a-b) and the silver(I) complexes (12a-b, 13a-b and 15a-b). Whereas, the 1,3-dioxolane substituted benzimidazole-based silver(I) acetate complexes (14a-b) demonstrated excellent potentials with both bacterial and fungal growth inhibition above 95%.

Risperidone (RSP) is an atypical antipsychotic drug which acts as a potent antagonist of serotonin-2 (5TH2) and dopamine-2 (D2) receptors in the brain; it is used to treat schizophrenia, behavioral and psychological symptoms of dementia and irritability associated with autism. It is a poorly water soluble benzoxazole derivative with high lipophilicity. Supramolecular adducts between drug substance and two methylated beta-cyclodextrins, namely heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM-beta-CD) and heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM-beta-CD) were obtained in order to enhance RSP solubility and improve its biopharmaceutical profile. The inclusion complexes were evaluated by means of thermoanalytical methods (TG-thermogravimetry/DTG-derivative thermogravimetry/HF-heat flow), powder X-ray diffractometry (PXRD), universal-attenuated total reflectance Fourier transform infrared (UATR-FTIR), UV spectroscopy and saturation solubility studies. Job’s method was employed for the determination of the stoichiometry of the inclusion complexes, which was found to be 2:1 for both guest-host systems. Molecular modeling studies were carried out for an in-depth characterization of the interaction between drug substance and cyclodextrins (CDs). The physicochemical properties of the supramolecular systems differ from those of RSP, demonstrating the inclusion complex formation between drug and CDs. The RSP solubility was enhanced as a result of drug encapsulation in the CDs cavity, the higher increase being obtained with DM-beta-CD as host; the guest-host system RSP/DM-beta-CD can thus be a starting point for further research in developing new formulations containing RSP, with enhanced bioavailability.
